LOUIS DAMARIN GREGG, 0F HACKENSACK NEW JERSEY, ASSIGNOR TO THE GREGG I COIIEPANY, LIMITED, OF HACKENSACK, NEVI JERSEY, A CORPORATION OF NEW YORK.

CAB-BRAKE.

To all whom it may concern:

Be it known that I, LOUIS DAMARIN GREGG, a citizen of the United States, residing at Hackensack, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Car- Brakes; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to car brakes, and more particularly to the support for the operating brake shaft or mast.

It has primarily for its object to provide a support which will have three bearings for the shaft thus affording greater stability and bracing effect for the shaft, and also afford a shelf for the ratchet and pawl or other means provided for holding the shaft with brakes applied, and a shelf that will sustain the brakechain, when chain is used, and serves as a guard to prevent the chain from dropping or slipping ofi the end of the shaft or mast when the chain is loose, or will serve as a support or guard for the lever or other means serving to connect the shaft with the brakes.

For the accomplishment of the foregoing and such other objects as may hereinafter appear the invention consists in the features hereinafter described and then sought to be particularly defined by the claims reference being had to the accompanying drawing forming a part hereof and in which,

Figure 1 is a perspective of a portion of a car with the improved shaft or mast support applied; Fig. 2 is a plan view of the support as it might appear in blank form.

In the drawing the numeral 1 designates a portion of a car body; 2 an end sill thereof; 3 a brake-shaft or mast; 4 a car coupling, all of any well known approved type of construction; and 5 the brake-shaft or mast support embodying the present invention.

The support embodies or contains three shelves 6, 7 and 8 which afford as many bearings for the brake-shaft which is sustained by the support, and thus the shaft is braced and its stability materially increased. The upper shelf 6 also affords a bearing or support for the ratchet 9 and locking pawl 10,

or other holding means provided for the brake-shaft, and the lower shelf 8 serves as a guard or rest for the connecting means between the brake-shaft and brakes, for instance, the chain 11, if a chain be used, so that the chain will not drop or slip off the end of the brake-shaft when loose but will rest upon the shelf which in practice is of material advantage.

The improved brake-shaft support may be cast or otherwise made, but preferably is formed of sheet steel, pressed into form. When made of pressed sheet steel, the sheet is by suitable dies pressed into a substantially U shape to form the top shelf 6 and middle shelf 7 with a connecting web 12, and is then slit as at 13 along one of the bends for a distance and the slitted portion bent downwardly to form the end wall or web lat and then under and parallel with the shelf 7 to form the shelf 8. If the comgleted support were flattened out it would present a blank of the form illustrated in Fig. 2 of the drawing.

The support is bolted or riveted to the end sill, and for that purpose the rivets or bolts or rods which secure the coupler in posi tion may be used, and in such case they would pass through the openings or holes 15 made in the web 12 and corresponding or registering with similar holes formed in the end sill. The support however may be attached to the end sill in any other appropriate manner, but when attached as specified, it avoids drilling or forming any additional holes for its attachment, and admits of the support being applied to cars originally put out without brakes but which may subsegugzntly be supplied and applied by unskilled a or.

It will be observed that the support does not in any wise interfere with the coupler, and as illustrated a portion of it fits behind the coupler so that it may be attached by the means which secures the coupler in place.

It is also obvious that the same features of construction may be employed whether the support is shaped to be applied at one side of the coupler or at the other side, the

novel features being the same in either case.

I have illustrated and described with particularity the preferred details of the invention but it is obvious that changes may be made therein including the web connections b t e n the shelves and the number of shelves and essential features of the invention be retained, as will occur to the skilled in the art.

Having described my invention and set forth its merits, what I claim is:

1. In car brakes, a support for the brakeoperating shaft comprising a shelf constitilting one bearing for the shaft and another shelf constituting a second bearing for the shaft and also a guard for the means eonnecting the shaft with the brake, the two shelves being connected together by a web located at the ends of the shelves to leave three open sides to the space between the two shelves.

2. In car brakes, a support for the brakeoperating shaft comprising an upper and a lower and an intermediate shelf, one above the other, the lower shelf constituting both a bearing for the shaft and a guard for the means connecting the shaft to the brake, and the intermediate shelf being connected to the lower shelf by a web located at the end of r the shelves to leave three open sides to the space between the two shelves.

3. In car brakes, a support for the brakeoperating shaft comprising an upper and a lower and an intermediate shelf, the intermediate shelf having web connections to the upper and the lower shelves, and there being an opening between the intermediate and lower shelves at the rear thereof for the passage of means connecting the shaft with the brake.

4. In car brakes, a support for the brakeoperating shaft comprising an upper and a lower and an intermediate shelf, the intermediate shelf being connectedbya web to the upper and to the lower shelf, one shelf and the web connecting it to the intermediate shelf being extended beyond one end of the intermediate shelf.

5. In car brakes, a support for the brakeoperating shaft comprising an upper and a lower and an intermediate shelf, the intermediate shelf being connected by a web to the upper and to the lower shelf, the web connecting one shelf to the intermediate shelf being extended beyond the end of the intermediate shelf.

6. In car brakes, the combination with the car end sill and car coupler, of a support for the brakeoperating shaft comprising an upper and a lower and an intermediate shelf and webs connecting the shelves, one of the webs being extended between the end sill and adjacent end of the coupler.

7. In car brakes, the combination with the car end sill, of a support for a brake-operating shaft having a portion to project between the car sill and end of a coupler to receive the fastenings employed for attaching the coupler to the car.

p In testimony whereof I aflix my signature in presence of two witnesses.
